I have never been a fan of pigeons. But over the last 3–4 months, I’ve watched a pair of pigeon mates settle and eventually build a nest on a column in the alley outside my building. Watching their relationship (pigeons mate for life) has steadily changed my view on our filthy urban birds.

Yesterday, it seems that one of my neighbors didn’t approve of this relationship and knocked their nest to the ground. There weren’t any eggs in it yet, so I went downstairs, collected the sticks, and put the bundle back. They’ll have to rebuild it, but maybe they will.

Who are the animals here?
